okay here you go.

first of all i went to the post office today with a da 100 with mufflers and ignition and weighed it.then i weighed the hh 100 on the same scale with mufflers and ignition.the results are as follows.

da weight---7 lbs 1oz

hh 100 weight--- 6 lbs 3 oz

the engine is still way rich with raw gas and oil dripping from the exhaust after i shut it down, the weird thing is that i have the high needle set at about 1/2 turn out and it is still sloppy rich. the rpm's as of now are 5700 rpm's with a 26a vess and an idle of 1500 very nice idle too i might add very smooth. i am puzzled by the high end being closed so far in and still being so rich. any idea's anyone? now my buddies da which we weighed today is also new, it has about 1 gallon through it and was taching 5800 with a 27 x 10 tbm prop. i have yet to put it in my new plane and i will be curious to see how much if any it picks up once break-in is complete. i plan on switching to mobil 1 2t synthetic after 5 gallons and then a 27a vess. i will keep everyone updated.

I thin k that your low needle is extra hyper rich, for this reason compensates the half turn of the high needle. Remember low afects high . Try Follow (sorry my english)

First set max rpm with the high
Go down 3/4 searching for rough work (if encountered lean the low
Go down 1/2 searching rough (4 cycle sound) lean the low

and after go gooze engine and tach rpm

well i am still having a problem getting it leaned out. the low end is at 3/4 out and the high is at 1/2 outand it's still so rich that raw gas is coming out of the exhaust and it has a burble on the top end like it wants to clean out but it can't. what gives????

PAPE

Try pinching the fuel line to lean it out se if that works. and take the RPM's

hi alfonso is a drop shipper for these motors he does not own the company that makes them..they are all hh brand motors,i got 2x100cc of alfy & have had nothing but problems.The key in the hub was to small so it went out of timming,the carbys dont sit flush on the manifold,mufflers dont stay on,both motors were diffrent colours lol,26x10 5300rpm & a mvvs 58 flys the same 33% plane around better,Im staying away from them till there sorted out which im sure they will do in the future
cheers glen

What do you base that on? I've dealt with him on a couple occasions, I had one of the original 100 engines, he replaced it with the new version for free, that doesn't sound like a drop shipper's responds to a engine that wasn't 100%. I don't know if he owns the company, but it seems that he has some connection with it and wants it to prosper.


I've not seen that problem.


Yes, I found that. When I get the engine I open them up, that's a easy fix I 400 grit paper on a sheet of glass and it takes 30 seconds to fix, or you could just use some RTV. Saving half on the engine you have to do a little clean up. From 3W this would be unacceptable, but because I open the engines to check them out anyway it's not a problem.


I get 6000~6200rpm using a Xoar 26x10, that's probably strong a 80cc, but I'm happy with mine new ones. I have two of his 50cc twins, 100cc twins, and a 50cc single, the 50cc Twin is a jewel of and engine, I like it the best. The twins should really be push in the scale market more, but some of use poor guys like having the choice of a inexpensive twin 100.

I have yet to see the logic here yet.


100cc that does what a ZDZ 80 will do any day and the ZDZ will come out a pound less. Can't really say much about the vibration because the ZDZ 80 is extremely smooth with very little vibration.

50cc twin that weighs more than the 50s out there and does 600-800 less rpm then the competition.


The only thing looking good here is the price... performance is not there.


Now you have the same engines being sold as "SV" series on another website and they are selling them even cheaper. So all you get is more cash in your pocket, a heavier plane, less performance, and you can say "I have a twin in my plane".

If it's all about money then buy a DL-50.. surely having a twin can't be enough?

grpro001

SV is just fake.GRPRO company never conclude any tractions with that guy in Hongkong.I also don't know where that guy buy engines from.But i can confirm that this guy will never has supplier to set up connection with him.That guy make engine market confusion to reach his evil inentions.Most of Chinese suppliers will stop relation with him.So hope everyone has a correct opinion of his actions

I think you're totally focused on HP/pound, in 3D forum that's probably appropriate. I just bought a Brillelli 366GT because it seems to win the HP/pound/dollar war The GrPro/LS does very well in the HP/dollar contest. As I wrote it would probably do better in a scale plane for weight, smoothness and packaging reasons, twins have a place. To say more negatively about the motor seems to be bashing it. It would not be your choice using your selection criteria, you've made your point, others have other criteria for choosing.

There seems to be a question of who is making the HH100t, Alfonso said he's not. Alfonso says he IS making the GrPro-LS Pro engines, and his dealings with me make me think he is.

STEVESRCWORLD is getting zero help with his HH100t's issues, I got great support with my LS Pro 100, (GR Pro), kind of makes you think twice about buying from China direct.[&o] With the support from LS Pro engines I got my engines running like tops and am very happy, STEVESRCWORLD on the other hand is struggling just to get his motor to run, and can't find any after market support, so much for HH engines.[:'(]

As I posted earlier, I too have had problems with a HH50 twin purchased from Hong Kong. My opinion now that I have disassembled the engine is that it was made from scrapped parts. Larry from LS Pro was very helpful selling me some replacement parts, and, examining his parts and the original parts really demonstrated the difference in quality.

i am sending mine back for a refund on it. this is my first and last time messing with no name china engines. it's worth the extra money to get a well known engine that you know will run and perform like it should. i think i will try a kroma 100.

soarrich

My Feedback: (98)

Kroma 100? First time I heard of one of these, I Googled it, interesting.

Did you ever think of the LS Pro, drop right in, great service, after market help when you need it. It won't put out the numbers of a DA100 or 3W 106, but it's $800 on you doorstep. Worst case you can send it back, but I've got 5 LS Pros and I'm happy, they aren't getting mine back!

WHAT KIND OF RPM'S ARE YOU GETTING ON THEM? I WANT TO RUN A 27A VESS PROP. THEY LOOK EXACTLY LIKE THE HH 100 THAT I HAVE NOW. DON'T THEY COME FROM CHINA ALSO?

Mitsu1

My Feedback: (13)

Steve ... Coming from China does NOT... automatically make an engine bad. You bought a HH100T, which according to GRPro Manufacturing's words ... "A poor copy of our GRPro 100 Twin".
Also, there are many Chinese built engines which are great performers. I own a Copperhead Venom engine, which is an American owned company, but produced in China, and its an awesome engine. The DL50 is an awesome engine, the GS65cc is an awesome engine ... and just a number of others. You didn't do enough homework before you bought. I own all the engines listed above except the 100 Twin, and they all are outstanding performers and values.

Steve your cap lock is stuck on, bad form.[&:]

I think I'm getting 6200rpm with a 26x10 Xoar, Larry who has the new larger carb was getting 6700rpm if I remember correctly with the same prop, and 6200 with the 27x10 Xoar.
To paraphrase Mitsu, Rolls Royce and the MG both came from UK.

STEVESRCWORLD

My Feedback: (23)

6200 with a 27x10 is what i'm looking for. but like i said the ls engine looks exactly like the hh and gr pro. do you guy's think that maybe they are all from the same place? like someone said in an earlier post i don't think there are three or four engine manufacturers in china rushing out to copy an under powered engine. i will research the ls engine more but from what i can gather so far they are no better than what i had in performance.

STEVESRCWORLD

My Feedback: (23)

oh yea,

i have spoken with alfonso and i am set up to buy from him. so if i understand correctly, the ls pro is made by gr pro in china? he seem's like a nice guy but i don't want to buy another engine that doesn't do what they say it will. i have a fpe 95cc single that turns a 26x10 mejzlik at 6400 and a 27a vess at 5600 and is a pretty fair amount lighter than twin's. i kinda don't know what to do???????????

Got my parts direct support from china (through Steven on E-bay). Sending the engine and parts to Ralph. Hopefully he can help me.

LS Pro and GR Pro are the same thing, my LS Pro engine's booklet says GR Pro. Larry was the first to import them into the country, I think he and a guy in Mississippi where the only ones suppose to be selling them in the US, I don't know what became Johnny reb, but LS still imports them from WangAlfonso.

As far as coping the GR Pro motors and not say 3W, if the cylinders where sourced in China for 3W I'm sure they would be copied like the Gr Pro engines. Like a lot of good engines the cylinder jugs come from another application, maybe chainsaws or something. Few RC engines are totally purpose built for RC, the best ones are, but their prices reflect that.

If 6200 with a 27x10 is what you're looking for the LS pro/GR Pro engine can do that.

Just so you know, I know Larry and have been flying with him for thirty years, I don't work for him, (I don't need no stinking job), and I buy my engines from him.

My Feedback: (13)

Soarich, the line from Mississippi was the CK Pro, and they were the same as the LS Pro, .. and both were from GRPro. These were here well before HH100T showed up. My flying buddy tested the CK Pro 100 twin over a year ago, as well as the 50cc twin. He found that both were really nice and smooth engines, but the 100cc was just underpowered. Since that time, the GRPro engine has been upgraded and the latest upgrades are said to bring the performance into respectable numbers.

I personally believe the HH100T is a copy of the GRPro 100 Twin because everyone that has a HH100T is complaining about it .. yet the only complaint I know of from the CK, LS & GRPro has been not enough rpm's on the 100, and this is suppoe sed to have been addressed. The GS65, 65cc single that I have is one easy first flip starter, that has plenty of power, and it is produced by GRPro as Mr. Wang confirmed for me. Its one of the best $300 secrets out there. As for copying ... just look at the ARF kits! You can find about 3 or 4 different Chinese ARF manufacturers buiding and selling what appears to be carbon copies of popular kits. Example ... a relatively poor quality ARF manufacturer named Flight Model .. produces an exact looking duplicate 50cc Yak 54 as the very popular Aeroworks 50cc Yak 54, yet they ARE NOT the builders for Aeroworks. This plane has the exact covering scheme and all! Aeroworks sells for $630 .. and the knockoff sells for $400. I have 2 of the Flight Model planes ... both have lousy China Cote covering, thin substandard aluminum wing tubes ... and one has a noticeably warped fuselage! ... As for the Yaks, without close inspection you'd swear they were Aeroworks models.

after i receive my refund i will give larry a call. i would prefer to save some money if possible but i want an engine that will have power that i expect from a 100. thanks for the help guy's.

Just found out the peak 100 twin. I think this one is the original, and all the others are Knock offs.
